The cable is projected forwardly of the post in two substantially parallel sections air at theapexes ofiwhich the barrier isfastened;

-' Thebarrier consists or "two metal "ribbons or flats-l2 fa'ste'ned at the apexes of I the suspension element by=means of clamps iii. The clamps; as best shown in Figures IO and lh eaeh comprise two lapping-members 13w and 1 I30 015 U-shaped form,: pivotally conneoted by E headed pins M;

The .pins are; held' against-vertical displacement bycotters 15in aperturesiat'their, projecting ends;

The fiatw I 2 of i the barrier is -disposed between the two members, free :forlongitudinalmovement and the clampis secured at the, respective :apex of the cable by drawing the latter through open-; ings .in v the. member iSaTand securing the latter in place bymeans of U-bolts I6 and nuts ll.

,Th'e'c'ables 8-a're, made into endless formiby" s plicing their lapping ends by means "or U-bolts l8 and nuts H), as shown in Figure 2. Distinctive features of the fence are that the barrier-members I2 are free for longitudinal movement, that they are pivoted for lateral movement relative ,to the suspension-elements, and that they are justed positions.

In a fence of the above-described construction, the barrier is free to give under impact by the inherent resilience of its two flats, by the movable connection of the latter with the suspension cables, and by lateral movement of the latter with reference to the respective posts.

, The form of the invention illustrated in Figures 4, 5, 12 and 13 differs from that hereinabove described, mainly in that the barrier is composed of a single plate or fiat 211 of greater width than either of the two ribbonlike flats I2. The suspension-element consists of a cable 2| connected with the post as before, but having a single forwardly projecting portion of substantially trapezium form.

The forward side of the cable lies flat against the rear side of the plate 20, and the latter is secured to the cable by a clamp 22 .which embraces the plate and which in divergently extending ends 2211, has openings through which the cable is passed. The clamp is secured at its ends to the cable by U-bolts 23, and, as before, the cable and the barrier are adjustable to aline the barrier with the surface of the road; The barrier is lengthwise movablerelative to the suspension-elements and the latter are spliced at the ends of theircables, as in the first described form. r

In the construction illustrated in Figures 7 and 8, the barrier consists of two or more cables 24 which are connected at the forward ends of suspension cables 25, by means of clevises 26. The suspension cables are supported and tensioned on the posts by the bolts 9 and) as in thebefore described-construction. .I'

In Figure 7, the forwardly projecting suspension cable is of trapezium form, as in the corn struction shown in Figure 4, and the two cables of the barrier are'supported at the forward corners of the suspension cables by the clevises abcve referred to. e

Each clevis has a U-shaped loop embracing the cable, and apertures at the ends of the loop through which the suspension-cable-passes. The clevises are secured to the suspension cable by U-bolts 21 applied to extensions at an endof their loops, and tightened by nuts 28.

It will be understood without further illustration that all of the above described adjustments and resilient movements of the barriers of the constructions shown'in Figures 2 and 4, are present in those illustratedin Figures 7 and 8.

The construction of Figure 8 differs from that of Figure '7 in that; the barrier is composed of three parallel cables instead of two, the third or intermediate cable 3| beingsuspended by means of. cables 29looped around bolts 30 on the posts, and connected with the cable'3l by clevises 32 of the same construction as those hereinbefore described.

The cables of the barriers of Figures 7 and 8 may constitute a barrier per se or they may form a support for a netting of the character shown in the patent and application for patent hereinbefore referred to. The barrier is anchored at its extremities to end posts of the series, as shown at 33 in Figure 1, preferably in a manner disclosed in a separate application, Serial No. 631,048, for patent filed simultaneously with the present application.

What I claim and desire to secure by Letters Patent is:
